Fig. 1a - Carybdea sivickisi

A mature female Carybdea sivickisi jellyfish. The long white speckled leaf-like structures are the female gonads (ovaries and gastric pockets). There are eight in total, of which only six are visible in the photo. Note also the boxy shape of the medusa (or jellyfish), which gives these jellyfish the fitting name "box jellies."
